TPMS sensors in your car often outlast the tires themselves. These units contain batteries designed to last 5 to 10 years. However, since the batteries cannot be replaced, the entire sensor must be changed when power runs out. Swapping sensors is not required during tire changes, yet it makes sense for vehicles aged five years or more.

Battery duration varies with type, heat exposure, fit quality, and driving habits. Sensors in parked cars tend to last longer because they enter sleep mode without motion. Cars facing severe heat or cold may require earlier replacement, as temperature extremes shorten battery performance.

Replacement costs add up quickly. Each direct sensor runs $70 to $150, plus $50 to $100 labor per wheel. Newer or luxury models cost even more. The job is straightforward for those with proper tools and experience, allowing capable owners to handle it themselves.

Removing and fitting new sensors mirrors basic tire service without full tire removal from the rim. Raise the vehicle, secure it on stands, loosen the lugs, and take off the wheel. Deflate the tire and break the bead to reach the sensor on the valve or inside the wheel.

Next, detach the old unit, fit the new sensor, reseat the tire, inflate it, and reinstall the wheel. Repeat for every tire, including the spare if present. After installation, recalibration is typically needed. Resetting may also be required after tire removal for repairs or rotations, or following a 12-volt battery change.

Calibration steps differ by make and model. Some Honda vehicles allow simple button sequences without special tools. Common steps include holding the TPMS button until the light blinks twice, then driving 30 minutes or longer between 30 and 60 mph. Other cars need dealer equipment or a dedicated scan tool for proper setup.

Owners can extend sensor life through regular tire pressure checks, fitting valve caps, and avoiding sealants. Prompt inspection is advised if the warning light stays on, flashes, or shows wrong pressures after manual checks. Faulty sensors reduce safety and may lower fuel economy.
